LONDON (AP) — After nearly a year of global travel and dozens of matches, most of Novak Djokovic's rivals are complaining about their mental and physical fatigue.

Not the Serb. He thrives in the rigors of a tough autumn finish.

Unbeaten since losing the U.S. Open final to Rafael Nadal, Djokovic joined Nadal in the ATP World Tour Finals semifinals, overcoming Juan Martin del Potro on Thursday.

After extending his winning streak to 19 matches with a 6-3, 3-6, 6-3 victory over the hard-hitting Argentine, Djokovic said he was playing the best tennis of his season.

"I just feel well at this particular part of the year," the six-time Grand Slam winner said. "I know most of the players are exhausted physically, mentally, emotionally, after a long season. But, you know, I try to find that as an opportunity for me, you know, to get extra motivated to kind of push myself to the limit and deliver the goods when needed."

Against del Potro, he delivered. In a very tight match, the Serb broke his rival twice, just enough to come out on top.

"He has one of the biggest serves in the sport," Djokovic said. "He has one of the most aggressive forehands. I just needed to stay tough."

Djokovic, undefeated in last year's Finals, improved to 2-0 in Group B after beating Roger Federer in the opener.

Federer made light work of Richard Gasquet for his first round-robin win, beating the Frenchman 6-4, 6-3 to boost his chances of making the semifinals for an 11th time.

Nadal qualified from Group A on Wednesday when he beat Stanislas Wawrinka to clinch the season-ending No. 1 ranking for the third time in his career.

Djokovic and del Potro couldn't reproduce their epic Wimbledon semifinal. The in-form players of the autumn exchanged groundstrokes early on, with Djokovic coming out on top of long rallies.

Playing more accurately and trying to shorten the points, del Potro soldiered on in the second set and was rewarded for his patience as he converted his first break point of the set in the sixth game thanks to a lucky net cord. The former U.S. Open winner then held his next two service games to force a third set.

In the third game, del Potro had 15-40 after Djokovic's first double fault of the match. The Serb saved the first break point with an ace and del Potro wasted the other with a botched forehand. The episode sapped del Potro's morale and he lost his serve at love in the sixth game. It was decisive.
